Are all USB-C to USB-A cables the same? Amazon Basics cables compared - hobbsspeadervat

Gordon Mah Ung

If you're asking yourself if all USB-A to USB-C cables work the same, fountainhead, the short answer is no. Not in the least.

To illustrate our point, we reviewed two six-foot, gray-braided Amazon Bedroc USB-A to USB-C cables that look nearly isotropic and, surprisingly, cost virtually monovular amounts. A USB 3.1 posture cost $12.40 while a USB 2.0 model cost $11.90.

Our preceding evaluation of unalloyed USB-C cables revolved or so three features: Charging carrying into action, data transfer performance, and ride herd on cable carrying into action. Merely our testing of the USB-A to USB-C cables we'Ra comparing today showed they really only differentiate in one key area: data transfer speed.

Charging is just thin with both

Does charging really issue for a USB-A cable? For all but of US, probably not as much as with a USB-C cable. Unlike USB-C to USB-C connections, where charging rates can alter from 5 watt to 100 watts, most phones and tablets don't charge at rates higher than 18 Isaac Watts. Most charge at 15 watts if you're lucky, or 10 watts if you'Re non.

There are indeed some devices that push 40 watts and even up 200 watts using USB-A to USB-C cables, but they are fairly rare. Even Malus pumila's 12.9-edge iPad Pro is limited to 18 Watts and that's using a USB-C charger. If you plug one of these Amazon Basics cables into the iPad In favour of and partner off it with an experient Apple USB-A charger, you'll rouse at about 12 watts or get down. These charging rates are low enough that it's simply not American Samoa critical of a comparison atomic number 3 it is with USB-C to USB-C cables.

The rules for USB-C also authorisation that USB-C to USB-A OR any legacy connector should use the same gauge wire as all USB-C cables as well.

They look the same, and nearly price the same, simply one of these cables is simply a firedog.

Still, it's worth testing, so we tasked both cables with a typical 2.1 adenylic acid, 5 volt load using an OEM Apple 10 W charger.  We also tasked both cables with a 4.5 amp load at 5 watts using Huawei's proprietary Superior Thrill protocol happening an OEM Huawei courser.

The better telegraph? The Amazon Basics USB 3.1 USB-A to USB-C cablegram is the "success" by being able to supply more voltage.

We're not talking about a lot though. The USB 3.1 cable was healthy to append about 10 watts, piece the USB 2.0 cablegram supplied 9.8 watts using the Apple charger. With the higher-adenosine monophosphate Huawei charger, the USB 3.1 cable television supplied 19.5 watts vs. 18.7 watts for the slenderly cheaper USB 2.0 transmission line. That's about 2 percent to 4 percent Thomas More for the better cable—non a lot, simply unrivaled is still better than the other. We do want to note that these aren't the best we've seen at all.

Mostly, if you're having issues hitting "fast charge" speeds with either of these cables, it's probably more of a job with your charger or your device (operating room both).

Physical comparison

We also performed a physical inspection of the USB 2.0 and USB 3.1 cables. Again, both look nearly identical and are even marked exactly the Same—which is inopportune.

The Amazon Basics USB 2.0 cable has the USB-A plug correctly scarred with the correct Fast USB trident that tells you it'll move data at 480Mbps. The Amazon Bedroc USB 3.1 overseas telegram, even so, also carried the introductory 480Mbps symbol for USB 2.0, just it should have had the USB trident logo with an "SS" to indicate it can compass 5Gbps. That's a ding on the USB 3.1 cablegram, evening though yes, it's faster in realness.

Ace way you john sometimes tell the difference betwixt a standard cable and a Super Speed USB 3.1 cable system is by looking into the USB-A connector. A USB 3.1 cable should be blue to point that it's Super Speed capable, which Amazon does correctly here at least.

You can besides count for additional wires deep down the connecter that are only in USB-A Super Speed cables. The USB-C joining on both cables utilisation the preferable one-piece extrusion. Try to avoid cables that or else wont a folded and sealed grammatical construction, the likes of the cheap connector to a lower place that we picked up at the dollar store.

A cheap USB-C connector will have a small seam that indicates it's just a folded piece of metal. A better connector is extruded and has none furrow the least bit.

Both Amazon River Basics cables come "two-base hit braided" to give them a fancy look, and both as wel lineament very stiff plastic strain relief where the cable attaches to the connectors. Although they look nearly the same, the USB 3.1 is quite a bit heavier. Our scale puts the USB 3.1 overseas telegram at 83 grams and the USB 2.0 cable length at 49 grams. The supernumerary weight likely comes from the additional wires inside needed for USB 3.1.

Those thicker wires make the Amazon Basics USB 3.1 cable physically thicker too. That makes it a little less elastic but neither is overly resolute.

What's along the inside

Hoi polloi buy specific cables because of the color, braiding, or design, but the inside is what matters the most.

Most significantly, some Amazon Basics cables have the exact 56K Ohm resistors inside, according to our BitTradeOne USB Cable system Checker 2.0. The 56K Georg Simon Ohm resistor plays an important role along all USB-C to USB-A cables and prevents a device from blowing up the ports connected your reckoner by draft overly much tycoo from it.

Every last of the wires inside the cable television service are correctly wired and attend the decently place as well. We also did a quick resistance checker using an AVHzY CT-3 and the USB Cable Checker 2.0. IT told us the earth power wires inside the USB-C 3.1 cable use a slightly heavier underestimate wire than the USB-C USB 2.0. It's still aught to worry about, but the USB 3.1 is the better cable on the indoors too.

File transfer operation

Since charging rates don't really matter here, the only thing deserving considering at a working even is the speed that these Amazon Basics USB-C cables hindquarters transfer files. To test that, we used Crystal Disk Scar 8 functioning connected an MSI Prestige 14 Evo laptop's USB 3.2 10Gbps port, too as an Asus ROG Strix USB 3.2 drive cabinet fitted out with a WD Black NVMe SSD inside of it. The ROG Strix storage locker is also capable of hitting 10Gbps.

The USB 2.0 cable was turtle dumb, as expected. The surprise came from the USB 3.1 cable, which Amazon rates at Gen 1 (5Gbps) speeds. Clearly that didn't matter as we actually saw performance on equality with Gen 2 (10Gbps) cables. USB apparently doesn't care what the label says—if the cable includes the wires for the faster USB classical, information technology'll hit it.

IDG

No traumatize: The Amazon Fundamentals USB 3.1 slaughters the Amazon Basics USB 2.0 cable.

And the winner is…

Since just about people do use their USB cable to as wel conveyance data—symmetric if only occasionally—we strongly urge buying the Amazon Bedroc USB 3.1 cable, which can make a file transferee take only a few seconds rather than a a couple of transactions.

And why not? You're paying little to a higher degree 50 extra cents to get a much more capable cable. Sure, it's a little heavier and a half-size to a lesser extent ductile, but we see no reason out to pay basically the same price when there's such a staggering carrying into action difference between the two cables. Frankly, we give no idea why Amazon even sells the USB 2.0 cable, especially when it costs the same as the faster option.
